This. invention -relate's to 'an improved means for opening 'the 'selvages, i. e., `removing `curl from the side edges, of a traveling fabric web. fand'further for maintaining the traveling'fabric web transverselytaut'and smooth.

In handling :a traveling fabric `web Ythrough 1various processing operations, itis Ahighly im- ;portant in fa number of instances tof-'maintain the web :open atvits .selvages and transversely taut -and ismooth. In a'gprinting machine, f for example, :if the Web'being printed is allowed to curl yat the selvages or is ltransversely.slack-"as it'ap- -proaches the printing station, the web -is very easily creased fasit passes through the printing rolls, so that l,an imperfect Vprinting impression results. A similarisituation exists in the Soaping or washing equipment .-used after printing in .Whichthe web 'is rungthrough squeeze rolls. if lthe web is allowed'to be creased atall by these squeeze-rolls, the printed colory spreads-badly and .causes defective cloth. Likewise, Iwhen a fabric web is being run over the heated cylinders of a drying range, if yanycreaseforfold occurs in the .cloth avmark is left which cannot be removed.

v'I-he problem of eliminating -folds or .creases .in these `and othersimilar instancesduring :the Yprocessing of a fabric web is provided for in aparticularly advantageous mannerby the selvage openingmeans of the-presentinvention. Brviey described, this slvage opening "means comprises pairs of rotatable and resilient disc elements arranged generally in face-'toface relation forI recivingtle'sel'va'g's f a tavelingfabric web be- 'tw'een'th'eir fac's 'adjacent aportionf ktheir peripliris's'o rthati-lie 'discs are 'rotated by fthe traveling fabric web, Yand nie'ansfor adjusting "the 'discelem'eiits f "eachpair'in angular relation rwth'respect to each oth'e'rso'thatthey exert an outward pulling and opening action'atthe'sel- "Vag'es as they'are rotated'by the'fabric'web. This arrangement makes it unnecessary toV provide any "separate operating'means for actuatingtlie'se'lvageopening imeans of the present invention, "and the adjustable Varran'g'ement of the "'dis'c eleime'nts further 'renders this selvage Jripening 'meanseasily adaptable vfor Vvuse Vin a y'variety 'of situations 4in web processing -'equip'rrie'nt jThe Vp'resz'ent linvention `Ais `described :further below in 'connection Vvwith the Laccompanying 'drawings in which:

'In Figs-1 and2 of the drawings, the traveling fabric iweb=is indicated'at'W, rand selvage open- ;ing means arrangedv according to thepresent inivention are 'shown at i0 Jand l0'.

The selvage `'opener lll' is exactly similar to the opener d,

except that it has Aa k.complementary arrange- Ainentfordisposition at the opposite selvage of the traveling-web asshowngin Figs. land 2. The arrangement of the selvage opener l0 is illustrated more-in detail inFigs. 3 to-f-,inclusive, and =as shown comprises ana-:assembly plate Vl2 tted with'a mounting bracket -I4 ,andcarryf lingtwo `support arms I6 extendingfromthe-.as-

sembly plates l2 inparallelv spaced relation. `The vsupportarms I6 are fitted withstuds -I- that are Vreceived -by theyassembly plate l2 and held in p1ace=bynuts2f0, so Ythat the support arms "iii may befrevolved on their --longitudinal axis, i. e., -the axis of Athe studs I8, when `the nuts vil!) are loosened, forgadjustment with respect -to theassembly plate V-I 2.

4`The supportarms I6 are slotted at ltheir exto press the-extension arms 2'2 Ayieldablyfinfone -direction, and thesupport arms I6 are further -ftted-with-setscrews 28 disposedtoextend into the slt I6' and bear on theshank of extension 404 usting the pivoted position of the Vextension arms `2`2wtoprovide adjustable Ystop means Vfor adarr'n s"2'2 agairist'the pressure of 'the'leaf springs T26. a The spaced'suppdrt arms |76 and pivoted 'exte'nsio'n'arms v22 are arrangedion each assembly plate f2 'With "ppsed dispositions, .and VWl'll'fthe parable resilient material, andare arranged `-in with each disc 34 supported independently for rotation about its center in a separate extension `arm 22. Also, the pivoted mounting of the extension arms 22 on the support arms I6, and the mounting arrangement on the assembly plate I2 which allows the support arms I6 to be revolved, renders the disc elements 34 universally adjustable so that the axisV of rotation of each disc element 34 .may be adjusted as desired in angular relation with respect to the other disc element 34 of each pair.

As a result the disc elements 34 of each pair may be angled so that they are arranged in con` tact with each other adjacent only a `portion'of their peripheries, and when the discs 34 are angled in this manner so that their contacting portions move outwardly in a direction generally transverse to the web W as they are rotated by the traveling web, an outward transverse pull is exerted on the web W. Thefresilient rubber disc elements l34 exert this outward pull inv a particularly effective manner because they can be adjusted for good gripping action at the selvages of the web W, and also because they are well adapted for handling any curl or fold which may occur at the selvages. The arcuate direction of the pull exerted by the contacting portions of the discs 34 as they are rotated by the vtraveling web W has a natural tendency to open and smooth out any such curl or fold at the selvages, but the resilient naturevof the disc elements 34 substantially improve this opening action. Also, the yielding pressure constantly exerted on the discs 34 from the leaf springs 2t furtherI enhances the resilient gripping eiect of the discs 34, and allows them to be adjusted nicely for-handling all types and conditions of fabric web.

I claim:
